The Replacement REPC314576 is an in-tank electric fuel pump module assembly designed for 1985–1991 Chevrolet S10 trucks equipped with 4-cylinder or 6-cylinder engines and a 20-gallon fuel tank. This complete module assembly includes the fuel pump, fuel sending unit, and all associated components needed for a full-system restoration of your fuel delivery system.

• Complete module assembly — includes the electric fuel pump and fuel sending unit in one kit
• In-tank electric design — mounts directly inside the fuel tank for efficient, consistent fuel delivery
• Compatible with 4-cylinder and 6-cylinder engines — designed to meet the fuel pressure requirements of both engine families
• OEM-matched specifications — engineered to replace original equipment with correct electrical connections, inlet/outlet positioning, and mounting dimensions

Replacing the entire fuel pump module assembly — rather than the pump motor alone — ensures that the sending unit, strainer, and wiring connections are all renewed at the same time, reducing the risk of repeat failures. This is especially important on higher-mileage vehicles where ancillary components are likely to be equally worn. Always clean the interior of the fuel tank and replace the fuel filter when installing a new pump module to maximize service life.
